This month we're proud to have a top rated JavaOne speaker presenting at MelbJVM.

Based on his talk at JavaOne last year, Nikita Salnikov-Tarnovski @iNikem (http://twitter.com/iNikem), was awarded the “Java Rock Star” badge of honour. He'll be presenting this talk at the next MelbJVM. The topic of which is something that every Java developer will encounter at some stage of their career.

Nikita's talk

"I will present a fairly simple web application, written using standard Java frameworks and libraries. What makes this application special is that it contains 8 different Permanent Generation memory leaks. They all are pretty standard, nothing obscure or weird. Each of them has a high chance to exist in your application as well. In fact the chances are so high I can bet a beer on the outcome.

I will describe each of these leaks explaining why this particular code leaks class loaders. I will also reason, if this was a deliberate technical decision and/or the implementation was just sloppy. I will also show how to fix it."
